Programmable, High-Speed, Multiple
Input/Output LVDS Crossbar Switches
24/MAX9135
General Description
Features
The MAX9132/MAX9134/MAX9135 high-speed, multi-
ple-port, low-voltage differential signaling (LVDS) cross-
bar switches are specially designed for digital video
and camera signal transmission. These switches have a
wide bandwidth, supporting data rates up to 840Mbps.
The MAX9132 has three input ports and two output
ports, the MAX9134 has three input ports and four out-
put ports, and the MAX9135 has four input ports and
three output ports. The digital video or camera signal
can go through the switches from an input port to one
or multiple output ports.
o Supports Up to 840Mbps Data Rate at Each Port
o Nonactivated Ports are in High-Impedance State
for Easy Port Expansion
o Programmable Preemphasis on LVDS Outputs
o Self Common-Mode Biasing on LVDS Inputs
o Three Selectable Approaches for Switch Routing:
I2C Interface
LIN Interface
The MAX9132/MAX9134/MAX9135 switch routing is
programmable through either an I2C interface or a
Local Interconnect Network (LIN) serial interface. In
addition, the MAX9134/MAX9135 provide pins to set
switch routing. These pins also set the initial conditions
for the I2C mode. To generate more input or output
ports, these switches can be connected in parallel or in
cascade.
Programmable Pins (MAX9134/MAX9135)
o
25ꢀV ESD Protection
o +3.3V Supply Voltage
o -40°C to +105°C Operating Temperature Range
The MAX9132/MAX9134/MAX9135 operate from a
+3.3V supply and are specified over the -40°C to
+105°C temperature range. The MAX9134/MAX9135
are available in a 32-pin (5mm x 5mm) TQFP package,
while the MAX9132 is available in a 20-pin (6.5mm x
4.4mm) TSSOP package. The input/output port pins are
rated up to 25kV ꢀSD for the ISO Air-ꢁap Discharge
Model, 15kV ꢀSD for the IꢀC Air-ꢁap Discharge
Model, and 10kV for the ꢀSD Contact Discharge
Model. All other pins support up to 3kV ꢀSD for the
Human Body Model.
